Transverse muffler exhausts

Hi. I have decided that I want a transverse muffler exhaust for my 1974 LT, mainly for the better ground clearence. The Dynomax super turbo I have now, gives absolute NO ground clearance. I have found 5 systems, but I need help to choose which one to buy. Opinions needed.
Thanks

I have that same muffler. I got the muffler and had custom pipes installed for $300 at a local muffler shop. I had replaced a flowmaster with this muffler, and im much happier with it, more mellow at idle and sounds wicked when you get on it.

^did the muffler shop use stainless? The price difference for stainless vs aluminized is a big factor. I always end up cheaping out and using aluminized and then hating how it holds up a few years later
